Why is there no time data attached to quotes on Google or Yahoo Finance?

When I access my portfolio data on Google Finance or Yahoo Finance, there is no date or time attached to the data for my stocks (I see a "Last price" column, but it doesn't say from when). Additionally, there is a "Change" column, but it doesn't say over what period. Any ideas why? Thank you.

1. Because it is not a real time report, but up to a 20 min. delay. So at 1:20 PM you are looking at the price for 1:00 PM. Times are better and it may only be a 5 min delay, but since Yahoo Finance is not connected into the exchanges, they can only get reports such as the news report.
